Be it known that we, FREDERICK lViLLiisn FARE, a subject of the King ofGreat Britain, and a resident of the city of Nottingham, in the countyof the said city, England, and JOHN CHARLES RionMoNn, a sub ect oi theKing of Great Britain, and a resident of Ohiiwell, in the county ofNottingham, have invented new and useful Improvements in illachines forThreadin and Unthreadin llizne-i\iachine Carriages, of which thefollowing in a specification.

This invention relates to improvements in machines designed to so dealwith bobbins and carriages of the kind used in lace-machines that theempty bobbin is removed from the cerriage, a lull bobbin inserted, thebobbin-threinl drawn through the carriagethrenl hole, thecarriage-spring placed upon the bobbin, and the bobbin and carriageremoved l'rom the machine, the object of the present invention being theconstructimi of a machine for automatically and successfully performingthe above-named operations.

in the drawings which are attached hereto, Figure 1 is a plan of alace-machine bobbin and carriage. Fig. '3 is a section on the line A A,Fig. 1. Fig. 3 is a front elevation of the machine. Fig. et is a partend elevation of the machine, showing in particular the bobbin and.carriage-reeeiving table and its actuating mechanism. Fig. 5 is a planof the bobbin and carriage receiving table. Fig. 6 is a section of themachine at the bobbin-removing mechanism, taken approximately on theline B B, Fig. 3. .Fig. 7 is a plan of part of the machine, showing inparticular the table for receiving the empty bobbins. Fig. 8 is asection of the machine at the bobbin-inserting mechanism, taken approximately on the line C C, Fig. 3. Fig. 9 is an elevation of themechanism used for placing the carriage-spring on the bobbin. Fig. 10 isa plan of the same. Fig. 11 is a sectional plan of the machine at theinserting mechanism, and Fig. 12 is a sectional eleva tion of themachine-table at the inserting mechanism.

The lace-machine carriage a is punched l'rom a sheet of metal and isprovided with nebs h, by which the carriage is moved to and fro in thelace-machine, and with pegholes c, by which the carriage is fixed inposition during the various processes of its manulaeture. The lower part(l of the carriage is of reduced thickness to allow 01'' it working inthe lace-machine combs, while the center part of the carriage is removedfor the bobbin 0. The lower part of the opening in the carriage has acentral rib or verge and at the upper part of the opening there is thecarriagespring g and thread-hole 72.. The bobbin 6 is composed of twometal plates, which are shaped to form a recess for the thread, having acentral hole 71, and are riveted together to form the bobbin.

The carriages (1 with the empty bobbins e, as taken from thelace-machine are placed in a carriagebox 1, which is shaped internallyto correspond with the carriages. This box is fixed to the machine-table3, and between the bottom of the box and the to of the table there is aspace sui'liciently large to allow 01 one carriage at a time beingremoved from the box by the carriage-plate 4, which is shaped at itsfront end to correspond with the outline of the carriage and is attachedto a slide 5, which is reciprocated by a cam 6 through the quadrantcam-lever 7, gearwheels 8 and 9, and gear-teeth on the under side of theslide 5. The cam-shaft 10 is carried by hearings on the standards 11 andon the tie-rail 12, and it is driven from the pulley 13 throughgear-wheels 14 and 15 and a friction clutch 16, which is coupled to theshaft by a cone 17, the movement of which is controlled by a handle 18.

hen the slide 1 is in its most bacluvard position at the left-hand endof the machine, the bobbins and carriages in the box fall onto the table3, and when the slide 1 commences its forward stroke the lowest bobbinand carriage in the box, which is held up to the end of the plate -'.lby a spring-linger 19, pivoted on the slide 5, is moved from thecarriagebox to the bobbin-removing mechanism, and the slide 5 comes torest. In this position the carriage is iixed and held by conicallyendedlisingpins 20, which are spaced to enter the carriage peg-holes c, areprovided with a lower li'Xed collar 21, an upper loose collar 22, andsprings 23 and 2a, and are fitted to slide in guides on the bracket Thecollar 22 is not 'ilXCtl to the pin 20, but operates as a bearing forthe spring 2-1, which latter holds it in position underneath the projection of the bracket 20, through which the pins slide. These pins areadapted to be ena cam 28 on the shaft 10, the fixing and holdingpressure being obtained by or through the springs 24, while the springs23 are used to raise the pins when the pressure of the springs 24 isremoved. The bracket 2O has the same outline at the back as the bracket30, to which it is pivoted at 29, and guarded by cheeks on such bracket.The bracket is fixed upon the table 3, and the bracket 20 is held fromaccidental movement by a pin or bolt 31, which also forms the axle ofthe lever 25. The bracket 20 is held stationary rela tive to the bracket30, but when the pin or bolt 31 is removed it may be swung back on itspivot 29, so asto raise the fixing mechanism clear of the table, ifrequired.

After the carriage has been fixed in position that half of the bobbinwhich is free of the carria- 'e-vergeis forced below the plane of thecarriage by a depressor 32, which is carried by an axle in the bracket33 and is actuated by a cam 34 through a lever 35, link 36, and lever37. The carriage-spring g is then forced off the bobbin by a pin 38,which is inserted between the edge of the bobbin and the spring, andsince the front edge of the bobbin is depressed the spring flies up ontothe top of the bobbin, when the pin 38 is removed. Thev pin 38 isadjustably mounted in the end of a lever 39, carried by an axle whichhas its bearing in the bracket 33 and is actuated by a cam 40 through alever 41, link 42, and lever 43. The bobbinremoving pin 44 then comesinto action. It enters the hole i in the bobbin and draws the bobbin ofithe carriage-verge f, and when free of the carriage the bobbin fallsdown the chute 45 into one of the boxes 46 on the bobbin-receiving table47. The bobbin-removing pin is adjustably mounted in the'end of anaxle48, carried by the bracket 33, and it is actuated by the cam 49 throughthe lever 50, link 51, and lever 52. The bracket 33 also carries an axlefor a lever 53, to which the stop -motion feelers 54 and are attached,either or both acting to stop the machine if the bobbin is not removedfrom the carriage, while the feeler 55 acts to stop the machine if thecarriage has by error been placed upside down in the carriage-box, thefeeler then coming into contact with the carriage-spring after thebobbin has been removed. The lever 53 is connected by a link 54 to alever 55 on a shaft 56, which can oscillate and slide in its bearingsand is provided with a lever 57, which has two pins 58 and 59. The pin58 rides upon the edge of a cam 60, (see Fig. 3,) which is provided witha recess and so timed that after the carriage has been fixed in positionthe feelers fall upon the bobbin and bring the pin 59 into the path ofan edge earn 61. If the bobbin is removed, the feelers fall through theopening in the carriage and the pin 59 falls below the cam 61 out if thebobbin has not been removed or the carriage has been placed in thecarriage-box upside down the pin 59 is held in the path of the cam .61.and the shaft 56 moved endwise. This movement of the shaft through thecollar 62 lowers the catchlever 63 clear of the catch 64 on the lever18, which is then actuated by the spring 65 to withdraw the cone 17 anddisconnect the shaft 10 from the clutch 16 and the driving pulley 13.

After the bobbin has been removed from the carriage the bobbin-re1novingmechanisms return to their normal position and the plate 4 is actuatedto push the empty carriage to the bobbin-inserting mechanism, in whichposition it is fixed and held by conicallyended fixingpins 20, mountedto slide in fixed and loose collars 21 and 22 of a bracket 66 andprovided with springs 23 and 24 and adapted to be actuated by the outerend ofa lever 25, pivoted at 31, through the link 26. The bracket 66 ispivotally connected to the bracket 30 at 29, but fixed thereto by thepivotpin 31. The bracket 66, in which the fixing-pins slide, alsocarries pins 67, to which the upper parts 68 of the insertingframe areattached, anda pin 69, carrying the presser-foot 70. The pins 67 and 69are also fitted with upper and lower collars and springs, and the lever25 is made long enough to actuate all the pins carried by the bracket66. After the carriage has been fixed at the inserting position theplate 4 makes its return traverse for another bobbin and carriage, whichis moved from the carriage-box to the removing mechanism and the bobbinremoved from the carriage, while the inserting operations are beingperformed 011 the carriage at the inserting position. Thesec- 0ndforward movement of the plate 4 moves the empty carriage to theinserting position, and the carriage at the inserting position is movedon to the delivery-table by mechanism actuated by the slide 5 andhereinafter described.

After the carriage has been fixed at the inserting position the upperparts 68 of the bobbin-inserting frame are pressed upon the top of thecarriage and over the ends of the carriage-verge. Under the carriage andattached to the table there are the under parts 71 of thebobbin-inserting frame, and between these two parts of the frame thebobbin for insertion is delivered and by such parts is held centrallywith regard to the thickness of the carriage, and therefore with thespace between the bobbin-plates opposite the ends of the carriage-verge.

The full bobbins for insertion are placed in a box or frame 72, which iscarried by a bracket 73 from the table 3. The". bracket is fitted with asliding block 74, which is actuated by a link and lever 76 from a cam77. The block 7 1 carries a plate 78, the front end of which has a verge79, similar to a carriage-verge, and the forward movement, of the plate78 pushes a bobbin out of the box 72 and delivers it into theinserting-frame The inserting-pin 80 then rises through the bobbin-hole'i and is actuated to force the bobbin onto the carriage-verge, thefoiwvard end of the bobbin sliding up the incline S1 and being liftedinto the plane of the carriage b the lever 82. The inserting-pin S0 islitted to slide vertically in the boss 83 of a slide 8% and to movehorizontally with such slide which is guided in a bracket 85, attached.to the under side of thetable 3. For actuating the pin 80 and slide 8iside plates 86 are provided, and these are guided by the bracket 85,coupled together bf, the axle 87 and actuated by the link 88 and thelever 89 from the cam 90. The first movement o'fthe plates 86 throughthe cans-slot 9.1 and a pin 92, connected to, the inserting-pin, raisesthe inserting-pin. through the bobbin, the slide 84 being held bv afriction-spring 93. The end of the stra it slot 94, also on the plates86, then coines into contact witha pin 95, which is attached to a block96, titted to slide inside the slide 8st and held with the pin at theend of a slot 97 in the slide 84 by a spring 97, which is strong enoughto resist the pressure required for the insertion of a bobbin, but wouldbe compressed if unt'lue resistance is offered to the insertion of thebobbin, and thus prevent damage being done to the bobbin. The plates 86are also provided with inclines or earn-surfacesOS, which act upon thelever 82 to raise the forward end of the bobbin into the plane of thecarriage and facilitate the complete insertion 0t the bobbin upon theverge of the carriage.

After the bobbin has been inserted the lever 25 is actuated to force thepresser-foot 70 into contact with the top of the bobbin and carriage, inwhich position it is held while the bobbin is threaded and thecarriage-spring placed upon the bobbin. The threadinghook 99 is thenraised through the carriage thread-hole It by the cam 100, through thelever 10], link 102, and slide 103, the bobbinthread then being in theposition of the dotted line 104. (See Fig. 11,.) The thread layer isthen actuated by the cam 106 through the lever 107 to push thebobbin-thread into the line 108 and into contact with 'the book 99,which afterward descends and draws the thread through the carriage-hole,the bottom of the bobbin-box being recessed to the line 109 to allow ofthis movement of the thread.

When the bobbins are placed in tlie bobbinboX, the ends of thebobbin-thread must be left long enough to allow of the thread ends beingdealt with when the bobbins and carriages are placed in thelace-machine, and to during the insertion of the bobbins they are placedupon a roller 1.10, which is carriedby a bracket 111 and rotated from apulley 112 on the shatt 1.0, through a belt 113, pulley 114, andgear-wheels 115. The surface of the roller is provided with strips ofcardclothing 115, bristles, or the like of such a nature and moved atsuch a surface speed that the thread ends are kept extended andseparated without being pulled oil' the bobbins, and at the same timethe threads are free to descend upon the surface of the roller as thebobbins are removed one by one from the bottom of the box. Thebobbin-box is also fitted with a threadclipping lever 116, by

which the threads from bobbins near the" bottom of the box are clippedwhile the lower bobbin is being moved from the boX, and such threads areheld by the clip from being pulled forward by the thread of the movingbobbin. The lever 116 is pivoted on the bracket 73 and actuated to openthe clip and allow the threads to fall by a piece 117 on the slide 78,the parts being timed to release the threads just before the slidereaches the end of the back stroke and to clip the threads again beforethe slide commences to move the bobbin out of the box. On the other sideof the bobbin-box is a bobbin clamping or holding device consisting of anumber of plates 118, carried byshanks 1 19,wl1ich are fitted to slidein a fixed bar 120 and held in their most forward position by springs121, as shown in Fig. 11. vidcd with pins 12 and are d'rawi'i back byinclines 123 on a slide 12 1, which is actuated by a cam 125 on theslide 78 through. a lever 126, the parts being designed to release thebobbins as the slide 78 completes its back stroke and during the timethe bobbins descend in the box 72.

After the bobbin has been inserted the spring g, Figs. 9 and 10, on theunder side of the bobbin, and to move it from this position onto theedge of the bobbin the 111tt('l.ll16 is "fitted with a slide 156, w? ichis guided in a bracket 157 and actuated from the cam 158, through thelever 159 and link 160. Ti e slide carries an adjustable pin 161 and islield in contact with tlte bottom of tlie bracket by spring-pins 162,and on to bottom there are pieces 163, so arranged in conjunction withthe bottom of the slide that a horizontal movement of the slide causesit to move vertically also and bring the pin 161 into close I loot10preventn1g the spring ilying onto the prevent such thread endsbecoming entangled 1 top of the bobbin.

The ends of the shanks 119 are prohaving its bearing in a bracket 145.

The bobbin and carriage delivery mechanism is carried by a block 127,which is fitted to slide in the same groove as the slide 5, and it isactuated from the slide 5 through a slotted link 128, which actuates themechanism to move the bobbin and carriage from the machine at the sametime as the emp ty carriage is moved from the removing mechanism to theinserting mechanism and to move the delivery mechanism into engagementwith the bobbin and carriage as the slide 5 completes its return stroke.Attached to the block 127 is a plate 129, which is shaped to fit againstthe lower edge of the carriage and carries an arm 130, to which a springclipping-pin 131 is pivoted, which pin rides round the carriage-net asthe delivery mechanism is moved to its clipping position. The arm 130also carries a bobbin-removing pin 132, which is designed to remove thebobbin from the machine if from any cause it has not been inserted. Thepin 132 is attached to acam-shaped plate 133, which is carried by a s;ring-arm 134 or its equivalent, which allows of the pin mounting thebobbin and carriage and passing behind. the p ece 68, which is inposition when the pin 132 moves to engage with the bobbin.

'lhe bobbins and carriages are moved by the delivery mechanism onto thechute 135, by which they are guided into boxes 136, on a table 137, andduring such movement the thread ends are drawn between a fixed knifeblade 138 and a blade 139, which is pivoted at 140 and held op en by aspring 141 and actuated to sever any thread ends which prevents thebobbin and carriage falling down the chute, by a cam 142 on thethread-layer lever 107 The bobbin-receiving table 47 and the bobbin andcarriage table 137 are provided with a convenient number of boxes 46 and136, respectively, and each of such boxes is of a depth sufficient toreceive a convenient number of bobbins or bobbins and carriages, and aseach box filled the tables make a partial revolution to bring anotherbox into the receiving position. The mechanisms used for actuating eachtable and for locking the tables in their oositions is of the same kindfor both tables, but is modified to meet the particular requirement ofeach table. To the under side of the tables a locking-plate 143 and aratchet-wheel 144 are attached, having as many notches and teeth,respectively, as there are boxes on the table, and these parts arefitted to revolve together with an axle Fitted to revolve on thetable-axle is a bevel-wheel 146, which carries a ratchet-pawl 147 and isin gear with a toothed quadrant 148. This latter is suitably pivoted andis actuated by a cam 149 on a shaft 150, which is driven by a worm-wheel151 and a broken worm 152 on the cam-shaft, the said worm being timed toactuate the table between the deliveries to it. The cam 149 also carriesa nose-piece 153, which acts upon the catch-lever 154 to move it clearof the locking-plate just before the table commences to move and allowit to fall into its locking position in time to stop the table at thedesired position, a spring 155 being connected to both levers 148 and154 for moving both in opposition to the movements of the cams.

The bobbin-box 72 and the thread-roller 110 may be parallel to orinclined to each other; but the roller is preferably inclined toward thelower part of the box to prevent the bobbin-thread mounting the top ofthe bobbin.
